elect all that apply.) on a circular path on a straight line on a parabolic path on an elliptical path Incorrect: Your answer is incorrect. (b) How can a driver steer a car traveling at constant speed so that the magnitude of the acceleration remains constant. (Assume that the road is level. Select all that apply.) on a circular path on a straight line on a parabolic path on an elliptical path Incorrect: Your answer is incorrect.
(a) We know that the acceleration of the car is given by :
a = change in speed / time taken
If the speed of the car is constant in a straight line, the acceleration of the car is zero because there is no change in the speed of the car.
(b) For the driver steer a car traveling at constant speed so that the magnitude of the acceleration remains constant, the driver should drive the car in the circular path. This is because, in circular path the speed of an object remains the same while its velocity changes.
